Mordenite composite membranes were prepared by means of coating a porous α-alumina support with nanosized mordenite seeds followed by hydrothermal crystallization.

Results showed that optically variable pigments can be prepared by coating Cr2O3 on the surface of the pretreated TiO2-coated mica.

Effect of TiO2-coating on structure and electrochemical performance of LiCo0.2Ni0.4Mn0.4O2

LiCo0.2Ni0.4Mn0.4O2, as the cathode material for lithium ion batteries, was modified by TiO2-coating.

The results suggest that a small amount of TiO2-coating does not change the crystalline structure, but considerably improves the electrochemical performance of LiCo0.2Ni0.4Mn0.4O2 in terms of capacity delivery and cyclability.

Thin films and multi-layered coatings comprised of different classes of materials are often used for various functional devices.

In addition, the residual stress distributions in the functionally and compositionally graded coatings were also analyzed.

Carbon fibres (CF) were modified with different oligomeric silsesquioxane (SSO) coatings to improve the interfacial property of carbon fibres/polyarylacetylene (CF/PAA).

The results show that the ILSS increases effectively and the effects on interfacial characterizations are distinguished from each other in accordance with the CF surface modified with different SSO coatings owing to the various structures.

AFM observations lead to the conclusion that an interfacial transition layer with different morphology and stiffness appears in CF/PAA composites after being treated by the SSO coatings of different structures.

There is a long distance for China to catch up with the developed countries in coating industry and the production technology of plastic-coated steel pipes.The approaches to develop plastic-coated steel pipe production, expand variety, widen application of coated pipes and open up markets etc. are discussed.

The output of paint in China was 928.4 thousand tons in l991,Setting the highest record and ranking the fifth in the world.The demand was around 800 thousand tons in 1993 with the supply surpassing the demand.It is estimated that the output will reach l.25 million tons in 1995 and 1.8～2.0 million tons by the end of this century.
